[0034] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0035] Central control equipment refers to devices that perform functions such as centralized control, coordination management, and information interaction in various systems. For example, home central control equipment is the control device of a smart home system. By integrating various smart devices in the home environment, such as smart lights and smart curtains, it enables centralized control and remote management of these devices.
[0036] Because central control equipment typically requires prolonged heat dissipation and is highly integrated, fans and cooling ducts are usually installed inside to cool the electronic components. However, since the cooling ducts are fixed, the heat dissipation path cannot be adjusted, resulting in low heat dissipation efficiency and uneven heat dissipation in some areas of the central control equipment.
[0037] Based on the aforementioned technical problems, this utility model embodiment is proposed. This utility model embodiment may include a base 1, a cooling fan 2, at least one lever 3, and a rotary driver 4. The base 1 includes a cooling cavity 101, an air inlet 102, and an air outlet 103, with the cooling cavity 101 and the air outlet 103 connected in an air path. The cooling fan 2 is located in the cooling cavity 101, and the air inlet of the cooling fan 2 is connected in an air path to the air inlet 102, while the air outlet of the cooling fan 2 is connected in an air path to the cooling cavity 101. At least one lever 3 is rotatably connected to the cooling cavity 101, wherein at least two electronic devices 61 of the central control device are distributed in the cooling cavity 101 located between the lever 3 and the air outlet 103. The output shaft of the rotary driver 4 is connected to the lever 3 to drive the lever 3 to rotate in the cooling cavity 101, adjusting the cooling path of the airflow towards the electronic devices 61, thereby improving the cooling efficiency and uniformity of the central control device.
[0038] Reference Figure 1-7 This utility model provides a heat dissipation device, which may include a base 1, a cooling fan 2, at least one lever 3, and a rotary driver 4. The base 1 includes a heat dissipation cavity 101, an air inlet 102, and an air outlet 103, with the heat dissipation cavity 101 and the air outlet 103 connected in an air path. The cooling fan 2 is located in the heat dissipation cavity 101, with its air inlet connected to the air inlet 102 and its air outlet connected to the heat dissipation cavity 101. At least one lever 3 is rotatably connected to the heat dissipation cavity 101, wherein at least two electronic components 61 of the central control device are distributed in the heat dissipation cavity 101 located between the lever 3 and the air outlet 103. The output shaft of the rotary driver 4 is connected to the lever 3 to drive the lever 3 to rotate in the heat dissipation cavity 101, adjusting the heat dissipation path of the airflow to the electronic components 61, thereby improving the heat dissipation efficiency and uniformity of the central control device.
[0039] In this embodiment of the invention, the heat dissipation device is part of the central control equipment and is used to dissipate heat from the electronic components 61 of the central control equipment. The central control equipment may include, but is not limited to, the following types: smart home central control equipment, conference central control equipment, security monitoring central control equipment, audio-visual entertainment central control equipment, and industrial automation central control equipment. For example, the central control equipment may be a smart gateway, a server, or an audio-visual host.
[0040] The heat dissipation device may include a base 1, a cooling fan 2, at least one lever 3, and a rotary actuator 4. The base 1 provides structural support and mounting for other components of the heat dissipation device. It has a heat dissipation cavity 101, an air inlet 102, and an air outlet 103. The air inlet 102 and the air outlet 103 are formed in the side wall of the base 1. The heat dissipation cavity 101 can form air passages with the air inlet 102 and the air outlet 103, allowing external airflow to enter the heat dissipation cavity 101 through the air inlet 102 to dissipate heat from the electronic device 61 located within the heat dissipation cavity 101. The airflow then exits the base 1 through the air outlet 103, thereby achieving air-cooled heat dissipation for the electronic device 61 of the central control equipment.
[0041] The cooling fan 2 provides the air pressure required for air cooling. The cooling fan 2 is positioned between the air inlet 102 and the heat dissipation cavity 101, meaning that the air inlet 102 and the heat dissipation cavity 101 are indirectly connected via the cooling fan 2. For example, the air inlet of the cooling fan 2 is connected to the air inlet 102, and the air outlet of the cooling fan 2 is connected to the air outlet 103. Thus, when the cooling fan 2 is working, it generates air pressure, causing external airflow to enter the cooling fan 2 through the air inlet 102 and then enter the heat dissipation cavity 101 through the air outlet. After the airflow in the heat dissipates heat from the electronic device 61, it flows out of the base 1 through the air outlet 103.
[0042] At least one of the aforementioned levers 3 is rotatably connected to the heat dissipation cavity 101. The lever 3 is located between the cooling fan 2 and the air outlet 103. That is, the cooling airflow entering the heat dissipation cavity 101 will pass through the lever 3 as it flows towards the air outlet 103. By adjusting the distribution position of the levers 3 in the heat dissipation cavity 101, the airflow from the cooling fan 2 to the air outlet 103 can be guided, thereby changing the heat dissipation path of the airflow in the heat dissipation cavity 101.
[0043] The rotary driver 4 outputs rotational motion and can drive the lever 3 to rotate. For example, the rotary driver 4 can be fixed in the heat dissipation cavity 101, and the output shaft of the rotary driver 4 is fixed to the lever 3. Alternatively, the rotary driver 4 is located on the end face of the base 1 away from the heat dissipation cavity 101, and the output shaft of the rotary driver 4 passes through the base 1 and extends into the heat dissipation cavity 101, where it is fixed to the lever 3. The length direction of the lever 3 coincides with the radial direction of the output shaft of the rotary driver 4. Thus, when the rotary driver 4 is working, it can drive the lever 3 to rotate, and through the guiding effect (also known as the airflow blocking effect) of the lever 3, adjust the airflow distribution to different electronic devices 61. For example, the rotary driver 4 may include a micro motor. Through the lever 3, the airflow is prevented from flowing through one electronic device 61 or flows through one electronic device 61 in small amounts, concentrating on dissipating heat from a specific electronic device 61. Thus, the heat dissipation path of the airflow to the electronic device 61 can be adjusted, thereby improving the heat dissipation efficiency and uniformity of the central control equipment.
[0044] The electronic components 61 of the central control device may include chips such as CPU (Central Processing Unit) and GPU (Graphics Processing Unit). These electronic components 61 may also include, but are not limited to, power amplifier chips, power management chips, and wireless communication module chips. At least two electronic components 61 of the central control device may be integrated onto the control board 6 of the central control device. For example, the end face of the control board 6 with the electronic components 61 may face the area corresponding to the heat dissipation cavity 101, and the shape of the control board 6 may match the cavity wall of the heat dissipation cavity 101, thereby achieving the sealing of the heat dissipation cavity 101.
[0045] An optional embodiment of the utility model, referring to... Figure 2 As shown, the thickness of the paddle 3 along the axial direction of the output shaft of the rotary driver 4 is the same as the thickness of the heat dissipation cavity 101 along the axial direction.
[0046] In this embodiment of the present invention, the thickness of the axially arranged paddle 3 is consistent with the thickness of the axially arranged heat dissipation cavity 101, which enables the paddle 3 to form a clearance fit with the cavity wall of the heat dissipation cavity 101 in the closed state. When the paddle 3 rotates radially, it can ensure that the airflow will not flow along the gap between the thickness direction of the paddle 3 and the thickness direction of the heat dissipation cavity 101, thereby improving the efficiency of flow rate regulation in the heat dissipation cavity 101 by rotating the paddle 3.
[0047] An optional embodiment of the utility model, referring to... Figure 1 and Figure 3 As shown, the air inlet 102 and the air outlet 103 are opposite to each other.
[0048] In this embodiment of the invention, the air inlet 102 and the air outlet 103 are arranged opposite each other, thereby extending the residence time of the heat dissipation airflow in the heat dissipation cavity 101 and facilitating the distribution of electronic devices 61 in the heat dissipation cavity 101. For example, the air inlet 102 and the air outlet 103 can be arranged directly opposite each other.
[0049] An optional embodiment of the utility model, referring to... Figure 1 and Figure 4 As shown, in the initial state, the length direction of the lever 3 is parallel to the heat dissipation airflow direction of the heat dissipation cavity 101.
[0050] In this embodiment of the present invention, the initial state can be understood as the state of the lever 3 when the heat dissipation device is activated. When the lever 3 is in the initial state, the length direction of the lever 3 is parallel to the direction of the heat dissipation airflow in the heat dissipation cavity 101. That is, the lever 3 is parallel to the flow direction of the airflow, thereby minimizing the obstruction of the heat dissipation airflow and allowing the heat dissipation airflow to flow evenly through the electronic device 61, thereby achieving uniform heat dissipation of the electronic device 61.
[0051] An optional embodiment of the utility model, referring to... Figure 5 As shown, at least one of the paddles 3 is driven to rotate by the rotary driver 4 and comes into contact with the cavity wall of the heat dissipation cavity 101.
[0052] In this embodiment of the invention, when the lever 3 abuts against the cavity wall of the heat dissipation cavity 101, it can completely block the airflow from the heat dissipation cavity 101 on one side of the lever 3. Therefore, the cooling airflow from the outlet of the cooling fan 2 can only flow from the heat dissipation cavity 101 located between the lever 3 and the un-abutted cavity wall (which is opposite to the abutted cavity wall) to the electronic device 61 in that area. This allows for air cooling of the locally distributed electronic device 61, thereby preventing the temperature of the locally distributed electronic device 61 from becoming too high and improving the heat dissipation efficiency of the cooling device.
[0053] In one or more embodiments, refer to Figure 5 As shown, when the lever 3 abuts against the cavity wall of the heat dissipation cavity 101, the length direction of the lever 3 can be set at an angle to the airflow direction. That is, the lever 3 is inclined relative to the heat dissipation airflow. The width of the heat dissipation cavity 101 gradually narrows from the direction near the heat dissipation fan 2 to the direction near the air outlet 103, thereby increasing the flow rate to the electronic devices 61 distributed in the local area through the setting of the lever 3.
[0054] In another embodiment, the lever 3 can be located at the center of the heat dissipation cavity 101 in the width direction, and the end of the lever 3 away from the heat dissipation fan 2 is connected to the rotary driver 4. When the rotary driver 4 rotates in a first direction, it can rotate the lever 3 to abut against one cavity wall of the heat dissipation cavity 101 distributed in the width direction. When the rotary driver 4 rotates in a second direction, it can rotate the lever 3 to abut against another cavity wall of the heat dissipation cavity 101 distributed in the width direction.
[0055] Therefore, the heat dissipation path can be adjusted by changing the rotation angle of the lever 3, and the flow rate of the heat dissipation airflow towards the locally distributed electronic devices 61 can be adjusted. For example, refer to Figure 4 , Figure 5as well as Figure 6 As shown, the rotation angle of the lever 3 can be between 0 degrees and ±90 degrees, where the initial rotation angle of the lever 3 is 0 degrees. This allows for focused cooling of the higher-temperature electronic components 61, while reducing or stopping cooling of the lower-temperature components 61. This improves the heat dissipation efficiency and uniformity of the central control device. Compared to a fixed heat dissipation path and flow rate for each electronic component 61, the heat dissipation device can also reduce the operating energy consumption of the cooling fan 2.
[0056] In one optional embodiment of the utility model, the paddle 3 is made of a thermally conductive material.
[0057] In this embodiment of the invention, the lever 3, made of thermally conductive material, can assist in absorbing the heat dissipated by the electronic device 61 during operation. This allows the airflow flowing from the outlet of the cooling fan 2 into the cooling cavity 101 to first pass through the lever 3 to dissipate heat, and then through the electronic device 61 to dissipate heat. The combination of the lever 3 and the cooling fan 2 improves the heat dissipation efficiency of the cooling device for the electronic device 61, optimizing the heat dissipation performance of the cooling device. Furthermore, the lever 3 can serve both as a guide and an auxiliary heat dissipation function.
[0058] In one embodiment, the thermally conductive material may include, but is not limited to, aluminum and aluminum alloys, so that the lever 3, while having an auxiliary heat dissipation function, also has the advantages of being lightweight. This allows the lever 3 to be extended in length without affecting the rotation of the lever 3 by the rotary driver 4, thus ensuring the service life of the rotary driver 4.
[0059] In one optional embodiment of the utility model, the surface of the paddle 3 is distributed in a scale-like pattern.
[0060] In this embodiment of the invention, the scale-like distribution can be understood as any two adjacent structural parts in multiple structures overlapping and staggered, forming a regular or irregular distribution on the surface of the lever 3. The scale-like distribution can increase the surface area of the lever 3, that is, increase the heat dissipation area in contact with the heat dissipation airflow, thereby greatly improving the heat dissipation efficiency of the electronic device 61.
[0061] In another embodiment, the surface of the paddle 3 is honeycomb-shaped.
[0062] In this embodiment of the present invention, the surface of the paddle 3 can be honeycomb-shaped. The honeycomb-shaped distribution can increase the surface area of the paddle 3, that is, increase the heat dissipation area in contact with the heat dissipation airflow, thereby greatly improving the heat dissipation efficiency of the electronic device 61.
[0063] An optional embodiment of the utility model, referring to... Figure 7 As shown, the heat dissipation device also includes at least two temperature sensors 5, each of which is adapted to each of the electronic devices 61 to detect the device temperature value of the electronic device 61 through the temperature sensor 5. The temperature sensor 5, the rotary driver 4, and the heat dissipation fan 2 are electrically connected to the control board 6 of the central control equipment to control the working state of the rotary driver 4 through the control board 6.
[0064] In this embodiment of the invention, the heat dissipation device may further include at least two temperature sensors 5, wherein the temperature sensors 5 are used to detect the device temperature value of the electronic device 61. The number of electronic devices 61 is matched one-to-one with the number of temperature sensors 5, that is, each electronic device 61 is provided with one temperature sensor 5. The cooling fan 2, the rotary actuator 4, and each temperature sensor 5 are electrically connected to the control board 6 of the central control device. The control board 6 receives the device temperature value detected by the temperature sensors 5 and controls the cooling fan 2 and the rotary actuator 4 to rotate.
[0065] In one optional embodiment of the utility model, the cooling fan 2 includes at least a speed-regulating fan. When the cooling fan 2 is a speed-regulating fan, its rotational speed can be changed, thereby increasing the air pressure and adjusting the heat dissipation flow rate to the electronic device 61, thus improving the heat dissipation efficiency of the cooling device. For example, when the electronic device 61 is operating for an extended period, the operating speed of the cooling fan 2 can be increased to increase the heat dissipation flow rate to the electronic device 61, accelerating the reduction of the internal temperature of the electronic device 61.
[0066] In one optional embodiment of the utility model, when at least two paddles 3 are provided, the number of rotary drivers 4 is consistent with the number of paddles 3, wherein each rotary driver 4 drives one paddle 3 to rotate.
[0067] In this embodiment of the present invention, the number of the paddles 3 can be multiple. For example, when at least two paddles 3 are provided, the rotation of one paddle 3 can be driven by a rotary driver 4 to adjust the heat dissipation path of the heat dissipation cavity 101. Thus, the airflow and velocity to a certain electronic device 61 can be adjusted.
[0068] In one optional utility model embodiment, when at least two paddles 3 are provided, the heat dissipation device further includes a drive gear set, the drive gear set including at least two meshing drive gears, at least two paddles 3 are respectively fixed to different drive gears, and the rotary driver 4 is fixed to one of the drive gears to drive at least two paddles 3 to rotate by a single rotary driver 4.
[0069] In this embodiment of the invention, the number of paddles 3 can be multiple. For example, when at least two paddles 3 are provided, all paddles 3 can be rotated by one rotary driver 4. For instance, rotational force can be transmitted through a drive gear set located between the rotary driver 4 and the paddles 3. The drive gear set includes at least two meshing drive gears, with each paddle 3 fixed to one of the drive gears, and the drive gears fixed to each pair of paddles 3 being different. Furthermore, the diameters of the different drive gears can differ, thereby allowing the rotation angle of each paddle 3 to be changed through a transmission ratio.
[0070] In summary, this utility model discloses a heat dissipation device, which may include a base 1, a cooling fan 2, at least one lever 3, and a rotary driver 4. The base 1 includes a heat dissipation cavity 101, an air inlet 102, and an air outlet 103, with the heat dissipation cavity 101 and the air outlet 103 connected in an air path. The cooling fan 2 is located in the heat dissipation cavity 101, with its air inlet connected to the air inlet 102 and its air outlet connected to the heat dissipation cavity 101. At least one lever 3 is rotatably connected to the heat dissipation cavity 101, wherein at least two electronic components 61 of the central control device are distributed in the heat dissipation cavity 101 located between the lever 3 and the air outlet 103. The output shaft of the rotary driver 4 is connected to the lever 3 to drive the lever 3 to rotate in the heat dissipation cavity 101, adjusting the heat dissipation path of the airflow towards the electronic components 61, thereby improving the heat dissipation efficiency and uniformity of the central control device.
[0071] This utility model embodiment also discloses a central control device, which includes a heat dissipation device and a control board 6 as described in any of the above utility model embodiments. The control board 6 integrates at least two electronic devices 61, which are distributed in the heat dissipation cavity 101 located between the lever 3 and the air outlet 103.
[0072] In this embodiment of the invention, the heat dissipation device is part of the central control equipment and is used to dissipate heat from the electronic components 61 of the central control equipment. The central control equipment may include, but is not limited to, the following types: smart home central control equipment, conference central control equipment, security monitoring central control equipment, audio-visual entertainment central control equipment, and industrial automation central control equipment. For example, the central control equipment may be a smart gateway, a server, or an audio-visual host.
[0073] The heat dissipation device may include a base 1, a cooling fan 2, at least one lever 3, and a rotary actuator 4. The base 1 provides structural support and mounting for other components of the heat dissipation device. It has a heat dissipation cavity 101, an air inlet 102, and an air outlet 103. The air inlet 102 and the air outlet 103 are formed in the side wall of the base 1. The heat dissipation cavity 101 can form air passages with the air inlet 102 and the air outlet 103, allowing external airflow to enter the heat dissipation cavity 101 through the air inlet 102 to dissipate heat from the electronic device 61 located within the heat dissipation cavity 101. The airflow then exits the base 1 through the air outlet 103, thereby achieving air-cooled heat dissipation for the electronic device 61 of the central control equipment.
[0074] The cooling fan 2 provides the air pressure required for air cooling. The cooling fan 2 is positioned between the air inlet 102 and the heat dissipation cavity 101, meaning that the air inlet 102 and the heat dissipation cavity 101 are indirectly connected by the cooling fan 2. For example, the air inlet of the cooling fan 2 is connected to the air inlet 102, and the air outlet of the cooling fan 2 is connected to the air outlet 103. When operating, the cooling fan 2 generates air pressure, causing external airflow to enter the cooling fan 2 through the air inlet 102 and then enter the heat dissipation cavity 101 through the air outlet. After cooling the electronic device 61, the airflow in the heat dissipates air through the air outlet 103 and exits the base 1.
[0075] At least one of the aforementioned levers 3 is rotatably connected to the heat dissipation cavity 101. The lever 3 is located between the cooling fan 2 and the air outlet 103. That is, the cooling airflow entering the heat dissipation cavity 101 will pass through the lever 3 as it flows towards the air outlet 103. By adjusting the distribution position of the levers 3 in the heat dissipation cavity 101, the airflow from the cooling fan 2 to the air outlet 103 can be guided, thereby changing the heat dissipation path of the airflow in the heat dissipation cavity 101.
[0076] The rotary driver 4 outputs rotational motion, which can drive the lever 3 to rotate. For example, the rotary driver 4 can be fixed in the heat dissipation cavity 101, and the output shaft of the rotary driver 4 is fixed to the lever 3. Alternatively, the rotary driver 4 is located on the end face of the base 1 away from the heat dissipation cavity 101, and the output shaft of the rotary driver 4 passes through the base 1 and extends into the heat dissipation cavity 101, where it is fixed to the lever 3. The length direction of the lever 3 coincides with the radial direction of the output shaft of the rotary driver 4. Thus, when the rotary driver 4 is working, it can drive the lever 3 to rotate. Through the guiding effect (also known as the airflow blocking effect) of the lever 3, the airflow distribution to different electronic devices 61 can be adjusted. For example, the lever 3 can be used to prevent airflow from flowing through one electronic device 61 or to allow only a small amount of airflow to flow through one electronic device 61, thus concentrating heat dissipation on a specific electronic device 61. Therefore, the heat dissipation path of the airflow to the electronic device 61 can be adjusted, thereby improving the heat dissipation efficiency and uniformity of the central control equipment.
[0077] The electronic components 61 of the central control device may include chips such as CPU (Central Processing Unit) and GPU (Graphics Processing Unit).
